Cleanup: minor changes to Python argument parsing loop
- Increment the argument index at the end of the loop.
Otherwise using the index after incrementing required subtracting 1.
- Move error prefix creation into a function: `pyrna_func_error_prefix`
so it's possible to create an error prefix without duplicate code.
This simplifies further changes for argument parsing from D14047.
